I agree fiverr is the biggest place to help people geting some low price works. I ordered some gigs in the fiverr in the last year. I have to say, a lot of sellers don't know the SEO. They provide the spam links not SEO links.
Someone may hate my words because I said the truth. They may lose the business. However, quality back links jobs will be survive.
Four Things You Need To Know When You Oder The Back Links Service
1 Don't order software back links like SENuke, Article Robot, Scrap Box,and X Rumor, because the database already full of spam links. Tons of back links from this software will cause your target URL be punished by Google immediately. I got one youtube url be put into the sandbox for the SENuke multilayer back links gig. If you don't believe me, you can try. No matter Link wheel, or Link pyramid.
2 Check the private blog network real PR and search engine indexed pages. A lot of sellers sell the fake PR blogs, and deindexed (banned) blog network. That will hurt your target url ranking.
3 Must careful on edu and gov back links. Some seller using cookie code to generate fake edu and gov back links.
4 Order the seller who has the SEO experience. A lot of sellers don't know what's anchor text, google indexed webpages, and back link quality. They even don't know what's SERP. They only provide back links but never give you right suggestion for doing SEO.
